For today’s costume idea, we’d like to add the bad attitude (and incisors) of the former to the dapper tux from the latter. Accessorize with incandescent fangs (because who wants regular ones once you’ve seen these suckers?) and some fake blood for dramatic effect. We might recommend a light spattering, rather than the full-on blood-soaked chin above—less likely to rub off on your date’s cheek at the end of the night.
